Overall, the models that fit the data place Saturn's core-envelope boundary a significant distance from the planet's center, roughly 60 percent of the way to the surface.

The core’s stability may help explain a long-standing puzzle: why Saturn emits more energy than it gets from the sun. After the planet formed, it was warm with the heat of its birth, but then it ...

A new paper suggests Saturn’s core is more like a fluid than a solid, and makes up more of the planet’s interior than we thought. With its massive rings stretching out 175,000 miles in ...

Scientists used Saturn's famous rings like a seismograph to study processes in the planet's interior. The researchers found its core must be fuzzy rather than solid, consisting of a 'soup' of ...

The numbers told them that Saturn’s middle must be a diffuse core, approximately 60 percent of the planet’s radius, containing 17 Earth masses of ice and rock.

Researchers now appreciate that gas planets are more complex than first thought. New findings have implications for our ...

A pair of Caltech scientists say that, based on seismic waves in its rings, Saturn likely has a "fuzzy" planet core made of ice, rocks, and lots of helium and hydrogen. The post Waves in Saturn ...

Previously, Saturn was thought to have a rocky, metallic core under all that frigid, fluid gas.“When the observations were limited to the traditional gravity field data, the compact core model ...

Now Saturn’s core has been illuminated. Older models depicted the planet as if it were a distinctly layered cosmic jawbreaker candy. Kronoseismology has revealed the messy truth.

Saturn has been found to have a core like ‘sludge’ that is potent enough to cause ripples across the planet’s rings. The astonishing findings contract what astronomers previously thought ...

The core of Saturn appears to consist of a ‘soup’ of rocks, ice and metallic fluids that slosh around and affect the planet’s gravity. NASA/JPL-Caltech/Space Science Institute.
